Diet Ultra Violet was a Mountain Dew flavor variant, and the first to be released exclusively in diet form. Its tagline was "Zero calorie DEW with a Flash of natural and artificial Mixed Berry flavors." while its planned FanDEWmonium tagline was "Mixed berry-flavored diet DEW with other natural flavors."
Diet Mountain Dew Ultra Violet was released for a 12 week period beginning in August 2009 and lasted through 2010, and was then discontinued. It also saw a comeback during the FanDEWmonium campaign and was a semi-finalist, losing to Diet Supernova and finishing in 6th place.
Diet Ultra Violet's flavor was a mixed berry flavored soda, and as its name suggests, it was violet in color. It was advertised as a "Flash of Natural and Artificial Mixed Berry flavors."
- Many fans who tried this flavor for its limited run found it very similar to Revolution, due to their similar mixed berry flavoring.
- Diet Ultra Violet was the first diet-exclusive flavor of Mountain Dew.
